According to this invention insulating wall board panels, preferably of the laminated or mulside walls and ceilings with wall board panels to ti-ply paper board type, are first nailed to the studding and headers of the wall or'ceilingstructure to be covered, said panels being arranged in courses so that the joints between the meeting edges of the panels contained in the same course are staggered in relation to the joints formed by the meeting edges of the panels contained in the adjoining course or courses. The laminated jpan'els should be of substantial thickness and stiffness and may consist of any desired number of plies of paper board or other fibrous material cemented together in the usual manner.

may be of any suitable length and width. In the preferred embodiment .the width of the panels applied to cover a vertical wall of a room or the like is preferably-such that three horizontally applied courses of the panels will completely cover the wall surface from the .floor line to the ceiling. been applied to a vertical wall structure in horizontal courses, they are covered by vertically extending single-ply panels, made of the same mate rial. The single-ply panels are butted .together After the laminated panels have I These panels are preferably of rectangular shape and in edge to' edge relation and are of sufiicient length to extend from the floor line to the ceiling.

The single-ply panels are relatively thin so that the vertical joints formed by and between their meeting edges are substantially as inconspicuous as the butt joints formed in applying wall paper.

The single-ply panels are normally flat and rigid so that it is asimple operation to apply these panels so'that their vertical edges may be butte'd together'to form a very thin line or joint. It is their meeting edges are staggered in relation to the vertical joints formed between the meeting edges of the laminated panels. The single-ply panelsare secured in place by pasting them to the outer surface of .the' laminated panels, the

The laminated panels arenailed to the ceiling structure in courses, with the panels of the one course staggered inrelation to the panels of-the adjacent. course or courses. The single-ply finishing panels are then pasted to the multi-ply panels and are preferablyof such. a length as toextend across v the ceiling from wall to wall.

It is also, preferred that the laminated panels and the covering single-ply panel besecured in place so that the grain of the single-ply panels is at right angles to the grain of the lam inated panels which they cover.

The present invention makes it feasible to use large headed halls for nailing both the marginal and the intermediate portions of the laminated panels to the studding-andheaders of the wall or ceiling structures since these nails are completely covered by the subsequently applied single-ply panels.

Proceeding now to a more detailed description reference will be had to the accompanying drawin awh n in+l Q r Fig. 1 is aperspectivei view showingthe studding and headers of a portion of a wall such, -forexample, asthe vertical wall of a room or similar enclosure. Y

Referring to the drawings, {designates a wall structure such as the wall of a a room or similar? enclosure, said structure comprising studding I" and headers According to thisinvention the inside of the wall structure 5 is first coveredlby view showing one of the laminated wall panels 8 arranged horizontally in superposed courses. The marginal portions of each panel 8 are fastened to the studding 8 and headers l by large headed nails as indicated at 8. The intermediate portions of the panels 8 are also nailed to intermediate studding'elements I as indicated at I I. This method of nailing the panels to the studding and header elements of the wall structure provides a very stiff insulating wall structure and is permissible by reason of the fact that the fastening nails are concealed from view by the single-ply finishing panels which are subsequently applied as hereinafter described. It

cemented together by interposed layers 82) ofasphalt. This construction is cited merely by way of example as the panels may consist of any number of plies, the principal consideration being that each panel be of substantial thickness and stiffness.

After the laminated panels 8 have been applied as shown in Fig. 2 the exposed surfaces thereof are covered by narrow single-ply panels M which extend from the floor to the ceiling and cover both the horizontal and vertical joints between adjacent laminated panels 8. The single-ply panels I! are normally flat and thin as shown in Fig. 5 and are comparatively rigid. These singleply panels are preferably made of the same material as the component plies 8a of'the laminated panels 8 and therefore have the same coefilcient of expansion. The grain of the single-ply panels II, when applied as shown in Fig. 3, extends in the longitudinal direction of said panels and is at right angles to the grain of the laminated panels 8. The single-ply panels are relatively thin so that the vertical joints l 5 formed between their vertical meeting edges are no more noticeable than the vertical joints between similar strips of ordinary wall paper.

It is also important that the vertical joints l5 formed betwen the single-ply panels H be staggered in relation to the vertical joints l1 formed between the vertical meeting edges of the laminated panels 8. After the single-ply panels have been applied, as shown in Fig. 3, they are sized.

structure in rows or courses.

In Fig. 6 I have shown a portion of a room having the wall board panels 8 and I4 applied to the vertical wall structure of the room as previously described in connection with Figs. 1 to 3 inclusive.

Fig. 6 also shows the method of applying the panelling to the ceiling. In this connection, it will be noted that the laminated panels 8 are nailed to the studding and headers of the ceiling Wherever practicable, the single-ply finishing panels I of the ceiling are made of sufllcient entirely across the ceiling from wall to wall. In some cases, of course, the finishing panels must be made shorter to take care of skylights or other openings.

While the laminated panels may be of any desired dimension, I have found it convenient to use panels 3 ft. in width by 10 ft. in length. The single-ply finishing panel should be of a length equal to the prevailing height or width of the wall to which these panels are applied. In practice I have found it convenient to use singleply panels varying in width from 18 to 24 ins.

Having thus described what I consider to be the preferred embodiments of this invention, it will be understood that various minor changes in the construction may be resorted to within the scope and spirit of the invention as defined by the appended claim.

Having thus described my invention, what I courses, each of said first mentioned panels comprising a number of layers of paper board cemented together to form a laminated panel structure and each of said finishing panels comprising a single layer of paper board made ,of the same material and of the same thickness as one of the component layers of said first mentioned panels, said finishing panels being butted to gether in edge to edge relation and being pasted to the outer surfaces of the first mentioned panels so that the vertical the vertical edges of the finishing panels are staggered with respect to some of the vertical joints formed by and between the vertical meeting edges of the underlying laminated panels.
